Specification of Letters Patent.

To all whom, it may concern:

Be it known that I, WALTER Sco'rr, a citizen offthe United States ofAmerica, and a resident of Plainfield, county of Union and 5 State ofNew Jersey, have invented certain new and useful Improvements in Paper-Feeding Machines, of which. the following is a specification.

y invention relates generally to, paper feeding machines, and has moreparticular reference to the sheet-feeding mechanism of a printing-press.In machines of this character thepaper has to be fed very rapidly totheimpression-cylinder and comes down .15 against the feed-gages locatedadjacent to thesame a reat deal of force. Inasmuc'has these feei l spacetherebetwee'n, the paper is frequently great impact. One ob' this, and fortln's purpgseI construct my ma chine with a pn'marydetention device ora primary gage located on the feed-board in This primary feed-gage ismade pre erably in the formota transverse bar extending all the",-.wayacross the feedeboard, or it may be a great number of contactingmade with points, or it may be made in the form of a plurality of'gagesor bars in alinement with each'othensoas to present practically a solidfront to 'the sheets. as they advance toward it.

' device serves to check the speed of the sheets and to stop theirprogress, some 'mean's, 'as a brush or other device, being used to thesheets the additional distanceto' the fee -'-gages proper and to theimpressionprinting-press embodymy-inve'ntionand afterward point out thenovel features in theclaims.

In the drawings I have embodied my in' v'ention'in a mac ine similar toone shown in -4 5 an a plication forLetters Patent filed by me ont e11th day of'A ugust, 1902,-Serial No. 119,212 but cha' esin constructionmay of course be made wit in the scope of the claims.

- Injthe said 'drawir igs, Figure 1.is a side 5 View of a part ofatwb-revolution rotary printing-machine, showing the impression and platecylinders, the feed-board, and ad indent parts. Fig. 2 is. a view ofthe; parts shown in. 1- from the opposite side 'of e'machine. Fig. 3is'a plan view of the -gages are usually located a considerable distanceapart, leavinga wide ect of my invention 1s to prevent,

primary feed-gage. Fig. 4 is a plan view of a modification of theprimary feed-gage shown in Fi 3. Fig. 5 illustrates still anothermodification of the primary feed-gage.

Similar letters of reference indicate corre- 6o sponding parts in thedifferent views.

A indicates a framework of a suitable construction in which the partsare mounted in the proper manner.-

B is the impression-cylinder,making two revolutions toeachimpressioinand C is the plate cylinder. The plate cylinder is lo,-cated below the impression-cylinder, so that the latter may be liftedoutof contact with the same at the proper intervals in a wellnown manner.

' The impression-cylinder B is mounted with the usual grippers to seizethe sheets, as' '11, mounted on the rod 22 and 0 erated by pins or camsin the usual way, an is further 7 5 provided with the throw-off fingersv, mounted on the rod 12 and operated by any means well known in theart. Above the. impression-cyl'inder are mounted the feed-gages pro er,I), on the shaft b of the framework, an the primary ga e or gages b onthe rod or shaft 6 On t is same rod 6" is also mounted thebinding-pulley l).

J is a shaft mounted in the framework carrying the cams j" and 7' and agear 7' meshing with the pinion 7' on the shaft of theimpression-cylinder, so that the shaft J makes one-half the number. ofrevolutions of the said impression-cylinder.

The primary feed-gagel; and bindingulley b are operated by means of thearm carried by the rodb", and provided with the roller 6 which restsupon the cam In like mannerthe shaft bfi-carrying the feedgages zproper,is operated by the frictionroller eoactingywith the cam on the shaft J.'In the present instance the feed gages proper, I), rest on an extensionof the feed-board K, while the primary gage' rests on the feed-boardpropcr. L

k s a brush for causing the sheets to travel down to the feedgagesproper and to the impression-cylinder after their speed has been checkedby the primary cage. The well known holding-bar in front gages forholding the sheet while the grippers open to seize it may of course alsobe used in addition to the 'foregoingelements. The sheets are fed downon top of the feedof both 1 5- roll ci'it into sheets, from a pile byany of the welbknown shectdeedets, or they-may be fed by hand in theusual way. When running at great speed, the automatic sheet feeders willpreferably be used. As the sheets advance they strike the primary gages7)", whereby their speed is checked or stopped without creasing ortearing the edge of the sheet. As soon as this has taken place the saidgages b" are raised, allowing the brush It to feed the sheet at areduced speed to the'gages proper, b, which letter at this moment areraised, allowing the sheet to pass on to the impression-cvlindcr, whereit is. seized by the grippers 51C The grippers l) carry the sheeteroundthe imprcssion.-cylinder, receiving an imprint while passing between thecylinders B and. (J. Whexl it reaches the upper side of the cylinder B,:l l'ter having received the said imprint,-and has passed to a pointbeyond the binding-pulleys b, the shhct is released by the liverydevice.

in Fig. 4 l have shown a plurality ofgagcs inst-cad ol the unbroken gageI)". 'lhcso "egos b are made with large contacting portions for thesheet, as shown, so as to present practically a solid front to theadvancing sheet. 'lhey operate in e mannersimilar to the "age b i H inFig. 5 1 have shown still another modilicetion of the primary gage. Inthis form it is made with sprocket-wheels Z on both sides-oi thefood-board and connected by the (fillitlil e, which carries alliI]SVUKSOlYfiEXi-CDXL ing bar a or other IHOLHS lor checl-zing thespeed, the parts being: so timed as to l)IlIl?,
